I am intrigued to see that Mathmos, the Poole based company that, back in 1963, launched that soon to become indispensable hippy accessory the lava lamp are celebrating the centenary of their founder Craven Walker.
Craven – his full name was Edward Craven Walker – was in some ways an unlikely inventor of the lamp that fascinated the counter-culture.
A former RAF pilot with a passion for fast cars, speed boats and helicopters, he was also a pioneering nudist who made a number naturist films that avoided the censor by being shot underwater.
He developed the first ‘Astro’ lava lamp after basing it on a design for a Heath Robinson style egg-timer that he’d seen in a pub in the New Forest. To his delight, and probably astonishment too, his lamp was an instant hit and when one of the Beatles ordered one it sales started to really boom. It took only a short while for the turn on, tune in, drop out generation in the US to become fixated with the new lamps with their trippy light show displays.
Craven was amused. Hearing that followers of underground heroes like Timothy Leary and Ken Kesey were hailing the lava lamp as some kind of alternative way to enlightenment, he announced: “If you buy one of my lamps you don’t need drugs”. It proved both a compelling and effective marketing slogan and the lava lamp has remained in continuous British production in Poole ever since. More info at www.mathmos.co
To celebrate the centenary Mathmos are giving away 100 of their candle powered Fireflow lava lamps over the summer. The lamp (pictured above) features the unique lava formulation perfected by Edward Craven Walker himself see here.
The company is also inviting people to post images of their vintage lava lamps and lava lamp stories at #ECW100. To enter the giveaway follow Mathmos on social media and look out for our #ECW100 competition post.
Meanwhile here’s a feature I wrote about Craven and the lava lamp that was published in Dorset magazine a few years ago. I think it’s worth another read.

With its gloopy, trippy, luminous light, the gently bubbling Astro lava lamp will forever be associated with the turn-on, tune-in, drop-out generation of the 1960s.
Organiser of the famed Woodstock Festival, Wavy Gravy, called it “Amazing!” adding with breathless enthusiasm that: “It causes the synapses in your brain to loosen up.”
In fact this ultimate addition to any 1960s hippy pad owes its origins to a Dorset based former World War Two RAF pilot, a remarkable imagination and that old business trick of being in the right place at the right time.
The man behind the lava lamp – currently celebrating its 50th anniversary – was the late Edward Craven Walker, a remarkable daredevil, inventor and pioneering naturist who shot the first underwater naked films to squeak past the censor.
Whatever else the dapper Craven (as he was invariably known) was, he was certainly no hippy. Not that he minded. Once aware that everyone from The Beatles to The Grateful Dead were making much of his new invention, he made a public statement: “If you buy my lamp, you won’t need drugs…It is like the cycle of life. It grows, breaks up, falls down and then starts all over again”
The hippies lapped it up and the endorsement of the counter-culture did Craven no harm at all. The lava lamp was actually inspired by spotting a Heath Robinson style oil-filled egg-timer in a pub in the New Forest.
Craven set about creating a lamp that worked on roughly the same principal – using heated oil, melted wax and an old orange squash bottle. After many modifications the lava lamp went into production at his factory in Poole in 1963. The company has been based in or around the town ever since.
The first two lava lamps on the market – The Astro and Astro Baby – immediately chimed with the emerging sixties hipsters but marketing was much tougher in those distant pre-internet days. In fact the original lava lamps were delivered around the country in a rickety old secondhand Post Office van.

Craven’s second wife, Christine Baehr, recalls how exciting life was when the lava lamp suddenly became the must-have accessory for the hip and the happening.
It appeared in cult TV programmes like The Prisoner and Doctor Who. No self respecting follower of fashion would be without one. It was even deemed an official design classic. Not that the trend-setters had a monopoly. A lava lamp was also featured in the decidedly uncool sit-com George and Mildred.
Down in Poole the Walkers suddenly found themselves at the sharp end of the swinging sixties. “Things seemed to move so quickly. It was terribly exciting,” says 69-year-old Christine who still lives on the Dorset-Hampshire border. “Psychedelia was a long way from our thoughts but it was the height of Beatlemania and one day a shop in Birkenhead phoned and said: ‘We thought you might be interested to know that Ringo Starr has just been in and bought one of your lamps.’
“That was it! We had no experience in marketing or PR but we didn’t waste any time in getting that particular message out. Things went absolutely crazy. We suddenly found ourselves in this bubble which just seemed to keep expanding. It was enormous fun.” That single Beatle endorsement had put them well and truly on the map.
Christine met Craven in 1960 when she was still in her teens. They married soon afterwards. She remembers him as a man “full of energy and ideas.” His controversial lifestyle and the notoriety he drew from his naturist films were, says Christine, of little concern: “It didn’t worry him at all because he felt there was nothing to worry about.”
Cressida Granger took over the Poole company in the early 1990s and now runs it as Mathmos – a name derived from the seething subterranean lake in the cult 1960s sci-fi movie Barbarella.
She has similar memories of the devil-may-care Craven. She first encountered him when she found a growing demand for lava lamps on a vintage stall she ran at London’s Camden Market. It occurred to her that she might be able to source the lamps direct from the Poole company. After doing a deal with the Walkers she turned the then declining company around and took over the business.
Cressida remembers Craven as a force of nature. “He used to fly helicopters, drive speed-boats and fast cars and once came running into the office shouting: ‘I’ve just bought a fire engine’. He was always inviting me to go in his helicopter. I used to think ‘If you hadn’t crashed so many Jaguars I might actually consider it’ But he was great fun: very bright and a very unconventional thinker.”
She recalls her initial business meeting with the Walker’s at their nudist camp at Matchams just outside Bournemouth but denies claims that she demanded that Craven and Christine keep their clothes on for the discussions.
“That wasn’t what happened at all” she laughs. “It was however suggested that I might like to take my clothes off. Let’s just say that I declined and the meeting went ahead with all us fully clothed…which was a great relief. ”
Although lava-style lamps are produced all over the world, Cressida Granger insists that the Mathmos lamps, still finished and filled in Poole, are unique, the precise contents a closely guarded secret.
So, I asked, has the secret formula been memorised by a select team and locked in a safe somewhere? I’m afraid not,” replied Cressida. “It’s written down and kept in a purple folder.” Silly of me. Of course, it would be.
To celebrate the 50th birthday Mathmos has launched a limited edition Astro lava lamp complete with certificate signed by Christine. The company has also produced a new heritage collection and has just completeda season of commemorative events at the London Design Festival. This included the unveiling of the world’s largest lava lamp – a 200-litre monster – at the Royal Festival Hall.
But it wont be the biggest in the world for much longer. At least not if the residents of Soap Lake City in Washington State, USA, get their way. There have been plans afoot for more than a decade to build a 60-foot lava lamp as a tourist attraction. The $1million dollar plan has yet to find funding though.
